Method for encoding information object and encoder using the same

Abstract

A method and apparatus are provided for encoding an information object. The method includes storing the information object in a buffer; generating a sampling set including bits selected from the buffer according to a predetermined rule and bits randomly selected from the buffer; generating control channel data including information on the sampling set; and modulating the sampling set and the control channel data.

What is claimed is: 
     
       1. A method for encoding an information object, the method comprising the steps of:
 storing the information object in a precoder buffer; 
 generating a sampling set including bits selected from the precoder buffer according to a predetermined rule and bits randomly selected from the precoder buffer; 
 generating control channel data including size information on the information object; and 
 modulating the sampling set and the control channel data. 
 
     
     
       2. The method of  claim 1 , wherein the control channel data further includes a sampling set number of the sampling set. 
     
     
       3. The method of  claim 1 , further comprising repeating and interleaving bits of the information object, before storing the information object. 
     
     
       4. The method of  claim 3 , further comprising encoding the repeated and interleaved bits of the information object by using a predefined code, before storing the information object. 
     
     
       5. An apparatus for encoding an information object, the apparatus comprising:
 a precoder buffer; and 
 an encoder configured to: 
 store the information object in the precoder buffer; 
 generate a sampling set including bits selected from the precoder buffer according to a predetermined rule and bits randomly selected from the precoder buffer; 
 generate control channel data including size information on the information object; and 
 modulate the sampling set and the control channel data. 
 
     
     
       6. The apparatus of  claim 5 , wherein the control channel data further includes a sampling set number of the sampling set. 
     
     
       7. The apparatus of  claim 5 , wherein the encoder is configured to repeat and interleave bits of the information object, before storing the information object. 
     
     
       8. The apparatus of  claim 7 , wherein the encoder is configured to encode the repeated and interleaved bits of the information object by using a predefined code, before storing the information object.
